saw it the other week and been searching to find out what it once was. i have considered buying it but in too minds (i can get it for $600)

ive got bigger pics and seems to be a custom job but well done it appears. just got me buggered as to what it might of been in its first life

What would you do with it, keep it as is, or create your own custom machine?
